In the intro this week, we talk about the addition of Gwen Jorgensen to the Chicago Marathon field, the results of the US 20K championship, and Colleen Quigley's latest results from Europe. 

Then at 23:20 into the episode, we shift to the final part of our series on "What does the race require?" This time we talk about the marathon including answers to questions like:

- How many 20 milers should you do? 

- How should you add pace work to your long runs?

- What should your workouts look like? 

And more... tune in to find out how to PR in your next 26.2.
